Roadworx 4120B

Budget Jaspers alternative - half price if not even less.
I'm used to putting things together - Jaspers stands take me less than an hour with tweaks - to get everything right and locked in place.
The Roadworx took way much longer - 3 full hours.
And I'm still not happy and need to tweak a few things.
The only way to mount it correctly is to inspect the product photos on this site while mounting and mimic them since the instructions it came with are useless and in tiny, illegible print.
I went to the hard ware store to get extra screws since the 5-sided set of screws don't actually turn - this since the holes they're supposed to fit in are 5 sided too... better believe it.

The measurements of the stand once it's been assembled are a bit off :
it's much wider and deeper than most synths are.
The first two levels are too deep and all levels have empty space on the sides.

There are no extra parts you can buy to make it sturdier - this is a shame - just one extra horizontal bar would make the Roadworx stand more reliable and almost up to snuff with Jaspers.
What Jaspers stands come with that makes them so much sturdier and less accident-prone are the "lock-in" attachments to the horizontal bars - making it almost impossible for the synths to tilt or fall forwards or backwards.
You can buy Jaspers holders and mount them on the Roadworx stand - they share the same diameter size.
You could potentially buy a Jaspers horizontal bar as well - but the lengths are different, so you would have to buy the 150 size and saw it off to compatible length.

Bottom line : decent quality stand considering the low price point.
